Systems and methods for a governance engine

ABSTRACT

A governance engine is provided that receives changes identified in dependencies in an enterprise and compares those changes to rule triggers, executing an output of a rule if a trigger is implicated. Related agents may examine the identified changes for new, potentially vulnerable or otherwise disallowed dependencies.

BACKGROUND

The present innovations generally address tools for programmatically enforcing rules governing software (and dependencies among such software) stored and executing on assets distributed throughout an enterprise. Modern enterprises rely on ever more complex mosaics and webs of software (including application code and databases) to manage, monitor and carry out their businesses. Often, for example, pieces of code in one area of an enterprise's software architecture are copied from or rely on data or pieces of code in a different area of the enterprise's software architecture.

These interdependencies have the benefit of making initial build-out more efficient and removing barriers to the flow of data within an enterprise during normal operation. However, maintaining data security, software quality standards and enterprise resiliency in such an environment becomes an extremely complex, time consuming and error-prone task if done manually or piecemeal.

Thus, there is a need for a way to programmatically enforce rules governing an enterprise's software and dependencies among that software. Inherent in many applications is also a need to efficiently analyze an enterprise's assets to identify dependencies to be used as a precursor to such an enforcement mechanism. Also, because assets may have dependencies that only become evident at run-time, there is a need for tools to perform a static analysis of assets as well as to dynamically analyze assets at runtime for dependencies.

In order to develop a reader's understanding of the innovations, disclosures have been compiled into a single description to illustrate and clarify how aspects of these innovations operate independently, interoperate as between individual innovations, and/or cooperate collectively. The application goes on to further describe the interrelations and synergies as between the various innovations; all of which is to further compliance with 35 U.S.C. § 112.

BRIEF SUMMARY

The subject of this disclosure relates to systems and methods for programmatically enforcing rules governing software (and dependencies among such software) stored and executing on assets distributed throughout an enterprise. As a precursor, some implementations also involve analyzing computer software to identify hierarchies, dependencies and other relationships among portions of the software of an enterprise.

In one aspect, a computer-implemented method for enforcing rules governing software in an enterprise, comprising, on a governance asset, executing a governance engine configured to receive at least one rule specifying at least one trigger and at least one output, receive a set of detected changes in dependencies in an enterprise from a delta agent based on an examination of subsequent dependency graphs, examine the set of detected changes for changes that implicate a trigger of a rule, and if a trigger is implicated by a change, execute the one or more outputs associated with the implicated trigger.

In one example, the governance engine is further configured to receive a set of potential vulnerabilities, compare any new dependencies contained in the set of detected changes for nodes identified in the set of potential vulnerabilities, and generate an output identifying any positive results of such comparison.

In another example, the governance engine is further configured to receive a set of restricted open source software nodes, compare any new dependencies contained in the set of detected changes for nodes identified in the set of restricted open source software nodes, and generate an output identifying any positive results of such comparison.

In another example, at least one rule includes more than one output and both outputs are executed if a trigger of that rule is implicated.

In another example, at least one rule specifies more than one trigger and an output of that at least one rule is executed if at least one of said triggers is executed.

In another example, at least one rule specifies more than one trigger and an output of that at least one rule is executed only if all of said triggers is executed.

In another example, a trigger of at least one rule identifies a node in a hierarchy with at least one node that is a child of said node, said trigger being configured such that the trigger is implicated if a change is detected in said node or any child of said node.

In another example, the governance engine is further configured to receive a set of at least one rule from a source outside the enterprise.

In another example, a trigger of a rule specifies a type of change necessary for an associated output to be executed.

In another aspect, a computer-implemented method for enforcing rules governing software in an enterprise, comprises executing a delta agent configured to receive dependency graphs from a synthesis agent, compare subsequent dependency graphs to identify any dependency changes in the enterprise, and output a set of detected changes to a governance engine; and executing a governance engine configured to receive at least one rule specifying at least one trigger and at least one output, receive a set of detected changes in dependencies in an enterprise from a delta agent based on an examination of subsequent dependency graphs, examine the set of detected changes for changes that implicate a trigger of a rule, and if a trigger is implicated by a change, execute the one or more outputs associated with the implicated trigger.

DETAILED DESCRIPTION

Embodiments of systems and methods for programmatically enforcing rules governing software (and dependencies among such software) stored and executing on assets distributed throughout an enterprise. While aspects of the described systems and methods can be implemented in any number of different configurations, the embodiments are described in the context of the following exemplary configurations. The descriptions and details of well-known components and structures are omitted for simplicity of the description, but would be readily familiar to those having ordinary skill in the art.

The description and figures merely illustrate exemplary embodiments of the inventive systems and methods. It will thus be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles of the present subject matter. Furthermore, all examples recited herein are intended to be for illustrative purposes only to aid the reader in understanding the principles of the present subject matter and the concepts contributed by the inventors to furthering the art, and are to be construed as being without limitation to such specifically recited examples and conditions. Moreover, all statements herein reciting principles, aspects, and embodiments of the present subject matter, as well as specific examples thereof, are intended to encompass all equivalents thereof.

In general, the systems and methods described herein may relate to improvements to aspects of using computers to programmatically enforce rules governing software (and dependencies among such software) stored and executing on assets distributed throughout an enterprise. These improvements not only improve the functioning of how such a computer (or any number of computers deployed in an enterprise) is able to operate by improving and maintaining data security, software quality standards and enterprise resiliency. These computer-implemented tasks are implemented to solve computer-specific problems. The problem and goal of trying to programmatically enforce software governance rules are not ones that exist outside of the computer or computer software fields or even in a generic computer. Rather, they are problems unique to and solved with respect to the particular assets (examples of which are described below) deployed throughout an enterprise and the software stored and executing on those assets.

Within an enterprise's software architecture, assets may be configured to store, execute and record the results of various pieces of software. Assets may be physical and/or virtual and examples include servers, desktop computers, laptop computers, smartphones, virtual machines, cloud computing environments or portions thereof, etc. Software residing in and/or executing on assets within the enterprise can include, for example, applications, databases, etc. and portions thereof.

In one embodiment, technology agents are distributed among the assets to analyze software residing and/or executing at those assets. In general, technology agents are configured to analyze one or more particular types of target software. For example, one technology agent may be configured to analyze binary Java code while another may be configured to analyze source code written in C and still another may be configured to analyze JSON databases.

Multiple complimentary technology agents may be configured to analyze the same type of software. For example, one technology agent may be configured to analyze popular third-party Java libraries while another technology agent at the same asset may be configured to analyze custom Java libraries. Technology agents may also be configured to analyze multiple types of software.

Technology agents may be configured to perform static analysis and/or dynamic analysis of software. The same technology agent may be configured to perform both static and dynamic analysis or such analyses may be performed by separate technology agents for a given software type. For example, one technology agent may be configured to perform static analysis of Java libraries as they are stored at an asset, while another technology agent at the same asset may be configured to dynamically monitor and analyze API consumers accessing Java APIs hosted by the asset.

Multiple technology agents may be bundled together in a core agent. Such a core agent may be distributed to an asset to provide a toolbox of different technology agents configured for specific uses, some of which may not always be necessary for analysis of the software at the asset. Alternatively, an asset may be provided with specific, individual technology agents corresponding to the types of software present and/or executing at the asset. Core agents may also include communication tools for assisting communication of results from technology agents. Core agents may also be configured to be installed at an asset, survey the software stored and executing at that asset and then retrieve technology agents from a repository that are configured to analyze the software surveyed at the asset. Core agents may also be configured to facilitate periodic updating of the technology agents should a newer version become available.

Technology agents may be configured to perform static and/or dynamic analysis of software and report their results to one or more synthesis agents configured to receive, aggregate and analyze results from each of the technology agents active in an enterprise. One or more synthesis agents may reside at an asset within an enterprise or may be hosted by a third party. For example, results from technology agents may be provided to one or more third party synthesis agents hosted on a third-party server or within a third party's cloud computing environment.

FIG. 1 provides an overview schematic of an exemplary embodiment. In the example shown, two exemplary assets 10 a, 10 b of an enterprise are depicted, with the understanding that the enterprise could include more assets that are not shown. Asset 10 a is shown as including three technology agents 12, 14, 16, with the understanding that the asset 10 a could include more technology agents that are not shown. Exemplary asset 10 a is shown as including in its non-volatile storage 24 two pieces of software 18 and 20. In the example of FIG. 1, software 18 is of type A and software 20 is of type B. Exemplary asset 10 a is also shown as executing software 22 from volatile memory 26. In the example shown in FIG. 1, software 22 is of type B.

In exemplary asset 10 a, the technology agents 12, 14, 16 are individually loaded onto the asset and pointed towards the software stored and running at the asset. In the example shown in FIG. 1, technology agent 12 is configured to perform static analysis of type A software (e.g., 18), technology agent 14 is configured to perform static analysis of type B software (e.g., 20) and technology agent 16 is configured to perform dynamic analysis of executing type B software (e.g., 22). Technology agents 12, 14, 16 may be configured to communicate their analysis results directly or another component of asset 10 a may be configured to perform this function.

Exemplary asset 10 b shown in FIG. 1 is shown as including a core agent 32 that includes technology agent 12, configured to perform static analysis of type A software (e.g., 18), technology agent 28, configured to perform static and dynamic analysis of type B software (e.g., 20 and 22, respectively), and communications tool 30, configured to communicate the analysis results of the technology agents included in the core agent 32.

As shown in FIG. 1, the executing software 22 on each of the assets 10 a, 10 b may be configured to access static and/or executing software (18, 20 and/or 22) at the other asset. These accesses, relationships and dependencies may be identified and analyzed by the technology agents (16, 28) configured to perform dynamic analysis of the executing software 22.

In the example shown in FIG. 1, results of technology agents' analyses are communicated to a synthesis agent 36 at a third party asset 34 for further analysis.

In another embodiment, software from assets in an enterprise may be evaluated by technology agents not co-located on an asset with the software. For example, software may be provided to one or more third party assets for analysis by technology agents hosted by the third party. Results from the technology agents may be communicated to one or more synthesis agents at the third-party asset(s) that perform the static and dynamic analysis.

In yet another embodiment, software may be analyzed by a technology agent at a different asset from that in which the software is being developed or at which the software is stored or performed. For example, software being developed in a development environment may be exported to an analysis asset within an enterprise for analysis by an appropriate technology agent. In another example, an asset in an enterprise is configured to host technology agents configured to analyze software residing and executing in an enterprise. In this example, technology agents may not be located at the same assets storing and executing the software.

It is important to note that throughout the present disclosure, when one asset is described as a particular type of asset (i.e., analysis asset, synthesis asset, etc.), that function is not necessarily to the exclusion of others. For example, a server may host technology agents that perform analysis of software received from a different asset (in this way functioning as an analysis asset) while at the same time receiving and synthesizing results from technology agents within the enterprise (in this way functioning as a synthesis asset), all while at the same time executing its own software unrelated to the dependency analysis innovations described herein. On the other hand, it is also possible that an asset serves only one function within an enterprise.

Static analysis performed by technology agents may comprise one or more different techniques for a given software type. Some techniques may be common among more than one software type and some techniques may be specific to and only relevant to one particular software type.

In one example, a technology agent configured to perform static analysis is configured to identify and examine source code or binary code as it is laid on disk. One category of software that may be examined is applications. In applications, a technology agent may be configured to identify and analyze database dependencies, annotations, and comments, for example, in addition to perform an analysis of the code itself.

In one example, annotations are analyzed to identify descriptions of database components and the names of any APIs that may be published or consumed by the software being analyzed. A technology agent may be configured to analyze all annotations within a piece of software or may be configured to analyze only selected annotations. In one example, annotations (or particular annotation types) may be identified by users manually as ones that should be analyzed by a technology agent. Users may manually identify for a technology agent how a particular annotation should be analyzed and/or provide a categorization of what information it may be expected to contain.

For example, the exemplary application code shown below uses the JPA annotation method to connect to a database.

import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table(name = “TABLE”) public class Table { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE) private Long id; @Column(name = “COLUMN0”) private String column0; @Column(name = “COLUMN1”) private String column1; @Column(name = “COLUMN2”) private String column2;

A technology agent configured to analyze such software may be configured to analyze the code for the bolded annotations “@Entity,” “@Table,” “@GeneratedValue” and “@Column” and record the contents of those annotations. This can be used by a technology agent or synthesis agent to build a hierarchy of the database. For example, from the code above, it is known that TABLE includes columns COLUMN_0, COLUMN_1 and COLUMN_2.

In example shown below, a portion of ServiceNow code includes a reference to a table.

myFunction: function ( ) { var rec = new GlideRecord(‘my _(—) table’); rec.query( ); while(rec.next( )) { gs.print(rec.number + ‘ exists’); } }

In this example, a technology agent may be configured to analyze the code, identify the bolded reference to the table “my_table” and record an association or dependency between the function “myFunction” (or its parent script if the function was not named) and the table “my_table.”

In example shown below, a portion of COBOL code in the program “PROGRAM.cbl” includes a reference to information in a table.

*Performs a SQL SELECT to get the firstname of the employee *with the employee number of 10. EXEC SQL SELECT firstnme INTO :Firstnme FROM employee WHERE empno = ‘000010’ END-EXEC.

In this example, a technology agent may be configured to analyze the code, identify the bolded reference to the table “employee” and record an association or dependency between the program “PROGRAM.cbl” and the table “employee.” The technology agent may also be configured to record that the table “employee” contains the column “firstname” and that the program “PROGRAM.cbl” includes an association or dependency on that column.

In another example, comments in a piece of software may be analyzed by a technology agent employing natural language processing to identify dependencies contained within the text of a comment in the software code. In one example, an analysis result returned to a synthesis agent may include both any results of such natural language processing as well as the text of the comment itself. The synthesis agent may be configured to receive such information and to logically connect any identified dependencies with the text of the comment in order to maintain the ability to display the comment to a user in connection with any identified dependencies. In this way, a user is provided the ability to confirm or double-check the dependency identification. A user may enter corrections to the identification of any dependency from the text of a comment as a means to correct the natural language processing function. For example, if the natural language processing is provided by artificial intelligence or a neural network employing machine learning capabilities, such corrections may be used to correct and improve the accuracy of the natural language processing.

The code itself may also be analyzed by technology agents to identify dependencies therein. In one aspect, to provide a foundation for subsequent dependency analysis, a piece of software may be analyzed to identify hierarchies within the code. Multiple aspects of the code may be considered a node and assigned a node identifier. For example, a library may be considered a node as well as a class or function within a library, as well as even a portion of code within a function. Other nodes may include databases, tables of a database, columns of a database, variables, etc.

Node identifiers may be, include, or be connected to a hash of content related to the node. For example, a library or function node may be identified based on a hash of the node's entire binary contents. In another example, function identifiers may be, include, or be connected to a hash of the function's signature. Such a function signature may include, for example, the name of the function, the return values of the function and the parameters of the function.

A technology agent may be configured to record a hierarchy of nodes within a piece of software. Such a hierarchy may be used in combination with or instead of a hash of a node's contents to identify the node. For example, a library may be identified both by a hierarchy of nodes within the library and a hash of the library's entire binary contents.

Once a hierarchy is identified, a hash may be computed of the node. Such a hash may include just the hierarchy information or may include the entire contents of the node (including or excluding the hierarchy information). A hash of a library's hierarchy may serve as an identifier for the library.

Static analysis may be performed by technology agents once or for a finite amount of time or on an ongoing basis. For example, static analysis may be performed only during development of an enterprise's software architecture. In another example, static analysis may be performed by technology agents on an ongoing basis. For example, static analysis may be performed every X number of minutes, hours or days. Upon a preset amount of time elapsing, static analysis may be performed again on all assets and nodes within an enterprise or only on a selected number thereof. For example, static analysis of different assets and nodes within an enterprise may be staggered such that each node is analyzed every 8 hours, but each node is not necessarily analyzed at the same time as or synchronously with other or all nodes in the enterprise. Execution of static analysis technology agents may be restricted, for example, based on time of day, current utilization of processing or network communication resources, etc.

In another example, a level of pre-analysis may be performed prior to a subsequent static analysis of a node. In one example, a node's hash may be compared to its hash from a previous execution of static analysis. If the hash is the same, further static analysis is not performed. In the example of a library, for example, a library may only be subsequently analyzed by a static analysis technology agent if a hash of its hierarchy differs from the previously recorded hash of its hierarchy. In another example, a library may only be subsequently analyzed if a hash of its entire binary contents is different than a previous hash of its binary contents. In this way, processing resources may be conserved by not performing static analysis of nodes that have not changed since the last time that it was performed.

In one example, static analysis of a function includes identifying any other functions that are called by that function. A result of such analysis (communicated to a synthesis agent) may be a directional vector between the identifier of the function node being analyzed and the identifier of the function node that is called.

In another aspect, applications may be subjected to static analysis by technology agents to identify APIs, databases (i.e. JDBC calls), message queues and the like that are called by the application. In one example, annotations in an application are analyzed to identify API call exposed or published therein. In connection with the dynamic analysis described in more detail below, dependencies adequately identified during static analysis may be omitted from analysis during dynamic analysis in order to reduce processing resources required. Alternatively, if dependencies can only be partially identified during static analysis, techniques such as byte code injection may be targeted to applications identified during static analysis as having possible dependencies for later analysis by technology agents during dynamic analysis.

For example, a technology agent may be configured to analyze software code for connections that are established from API consumers to API publishers. Portions of exemplary Java application code containing an API call from an API consumer to an API publisher is shown below.

@Service public class Consume {  @Value(value = ″${ip_address}″)  private String ipvalue;  public void crosscode( ) throws IOException { URL conURL = new URL(″http://″+ipvalue+”/api/call″); HttpURLConnection conn = null; try { conn = (HttpURLConnection)conURL.openConnection( ); } catch (IOException e) { e.printStackTrace( ); } conn.setDoOutput(true); conn.setRequestMethod(″GET″);

In this example, a technology agent may be configured to dynamically analyze the code to identify API calls by identifying “conURL” references in the code, as shown in bold above.

Similarly, a technology agent may be configured to analyze software code for APIs that are published by API publishers. Portions of exemplary application code publishing an API is shown below.

public class Assetcontroller extends BaseController { @RequestMapping(value = “/api/v1.0/listAssetsWithTechType”, method = RequestMethod.POST, consumes = MediaType.APPLICATION _(—) JSON _(—) VALUE, produces = MediaType.APPLICATION _(—) JSON _(—) VALUE) public SearchAssetsResponse listAssetsWithTechType(HttpServletRequest httprequest, ListAssetsTypeRequest request) throws DatabaseException { . . . }

In this example, a technology agent may be configured to analyze the annotations in the byte-code to identify published APIs, as shown in bold above.

In a similar example, a portion of .NET code is shown below that identifies a connection from an API consumer to an API.

namespace EdinaCosumer.Controllers { public class Consumercontroller : ApiController { [System.Web.Http.HttpGet] [System.Web.Http.Route(“api/index/consume”)] public string Index1( ) { string p = ConsumerController.FatDateNow( ); return “Consumer Calling successfull + ” + p;  } . . .

In this example, a technology agent may be configured to identify the “system.web.http.route” call and extract the “api/index/consume” string as the API endpoint.

Static analysis of databases may include, for example, analysis of database schemas to identify dependencies among tables, columns, views, indexes, stored procedures, etc. For example, one technique that may be employed by technology agents is to identify database configuration files and to analyze such files for connections between databases. For example, an ORM database configuration file may identify relationships between databases and between elements of databases. Static analysis of databases may also include analysis of connection logs to identify applications and/or functions that have previously accessed specific aspects of the database.

For example, a technology agent may be configured to analyze Hibernate (a Java framework used by Java applications to interact with databases) configuration files. Portions of an exemplary Hibernate .cfg configuration file are shown below.

<?xml version=“1.0” encoding=“utf-8”?> <!DOCTYPE hibernate-configuration PUBLIC “-//Hibernate/Hibernate Configuration DTD 3.0//EN” “http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd“> <hibernate-configuration>  <session-factory> . . . <property name=“hibernate.connection.url”>jdbc:mysql://localhost:3109/cros scode</property> . . . <mapping resource=“com/crosscode/common/contact.hbm.xml” /> <mapping resource=“com/crosscode/common/inventory.hbm.xml” />  </session-factory>  </hibernate-configuration>

In this example, a technology agent may be configured to identify the bolded hibernate.conneciton.url and resource mapping information from the code. It should be noted that the “localhost” placeholder may be replaced by the technology agent with an IP address of the asset prior to communication of the analysis result to a synthesis agent. From this analysis of the .cfg file, the technology agent may be pointed to relevant .hbm configuration files (for example, “contact.hbm.xml” or “inventory.hbm.xml” shown above).

Portions of an exemplary Hibernate .hbm configuration file are shown below.

<?xml version=“1.0” encoding=“UTF-8”?> <!DOCTYPE hibernate-mapping PUBLIC “-//Hibernate/Hibernate Mapping DTD 3.0//EN” “http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd”> <hibernate-mapping>  <class name=“com.hibernate.contact” table=“contact”>  <id column=“ID” name=“id” type=“java.lang.Integer” />  <property column=“NAME” name=“Name” type=“java.lang.String” />  <property column=“EMAIL” name=“email” type=“java.lang.String” />  <property column=“PHONE” name=“phone” type=“java.lang.String” />  <property column=“CITY” name=“city” type=“java.lang.String” />  <property column=“STATE” name=“state” type=“java.lang.String” />  </class> </hibernate-mapping>

In this example, the table and column information is analyzed and extracted by the technology agent.

In the example shown below, a portion of software code includes a JDBC call that establishes a connection to a database.

public class OracleDatabaseRemote { public static void main(String[ ] args) { try { Class.forName(“oracle.jdbc.driver.OracleDriver”); Connection con=DriverManager.getConnection(“jdbc:oracle:thin:@host:1521:oracle ”,“user”,“pass”); . . .

In this example, a technology agent may be configured to analyze and extract the connection information shown in bold above. A technology agent performing subsequent dynamic analysis may be configured to use this extracted identification of the database connection to perform its dynamic analysis of the execution of code using this connection.

In another aspect, technology agents may be configured to perform dynamic analysis of software that is executing at the same time as the analysis is being performed. Technology agents configured to perform dynamic analysis may perform such analysis on all software in an enterprise or on a selected subset of software. For example, while static analysis may be performed on all or nearly all of the software in an enterprise for which technology agents have been configured, only a subset of such software may be dynamically analyzed by technology agents (for example, only Java or .NET applications).

In one aspect of dynamic analyses that may be performed by technology agents, API consumers may be identified and analyzed. For example, popular libraries may be identified before commencing dynamic analysis and calls to those libraries may be logged during run-time as a dependency between the source of the call (e.g., IP address, asset name, consumer method, application and/or function) and the library and function within the library. In another example, calls to all libraries may be monitored and analyzed. In still another example, libraries may be monitored for calls and popular libraries may be identified for dynamic dependency analysis. In this example, processing resource requirements may be decreased over monitoring all libraries or even a pre-selected set of libraries where some may not be utilized as much as others.

In another aspect of dynamic analysis, message queues may be monitored by one or more technology agents to identify producers and consumers of messages. For example, a Kafka technology agent may be employed at an asset to monitor production and consumption of messages in a Kafka message queue. In another example, a technology agent may be configured to analyze publish and consume libraries that interface with message queues to identify dependencies. A result of a dynamic analysis of a message queue may contain, for example, a list of topics that are published to or consumed from as well as an identification of each producer and/or consumer.

In the example shown below, a portion of software application code includes a connection made by a Kafka consumer to message topics.

private KafkaConsumer<String, Strings consumer; public void start(String topicName) throws InterruptedException {  Properties props = new Properties( );  props.put(“bootstrap.servers”, “localhost:9092”); . . .  KafkaConsumer<String, String> consumer = new  KafkaConsumer <String, String>(props);  consumer.subscribe(Arrays.asList(topicName)); . . .  } } }

In this example, a technology agent may be configured to identify the code shown in bold above and monitor the consumption of Kafka topics established thereby in real time during dynamic analysis.

Similarly, in the example shown below, a portion of software application code includes establishment of a Kafka topic that is produced.

. . . import org.apache.kafka.clients.producer.KafkaProducer; public class KafkaProducer { public static void runProducer(String topicName, int i) throws InterruptedException, IOException {  Properties props = new Properties( );  props.put(“bootstrap.servers”, “hostname:9092”); . . . Producer<String, String> producer = new KafkaProducer <String, String>(props); ProducerRecord prodRec= new ProducerRecord<String, String>(topicName,  Integer.toString(i), Integer.toString(i));  producer.send(prodRec); . . .  }

In this example, a technology agent may be configured to identify the code shown in bold above and monitor the production of the Kafka topic established thereby in real time during dynamic analysis.

In yet another aspect of dynamic analysis, database calls may be monitored and analyzed to identify which aspects of a database are interacted with by software within an enterprise, including the nature of such interaction.

Results that may be communicated from technology agents to synthesis agents include, for example, hierarchy information describing the hierarchy of nodes within an enterprise as well as dependency information describing which nodes are dependent on which other nodes (as a producer or consumer or both). Synthesis agents receive these results from among technology agents at an asset and from among the assets in an enterprise. As discussed above, core agents may assist in facilitating communication of analysis results from an asset to one or more synthesis agents. For example, a core agent may be configured to collect analysis results from technology agents at an asset, encrypt them, and then communicate the encrypted results to a third-party server at which a synthesis agent decrypts them and performs its work.

Synthesis agents may be configured to compile dependency analysis results received from throughout an enterprise in a relational database. Technology agents may be configured to include with their results time information such that synthesis agents are provided the ability to map changes to the results over time. The end result of the one or more synthesis agents is a dependency graph (in as many dimensions as is necessary) that records the hierarchy and dependencies among all nodes in an enterprise.

Synthesis agents may be configured to identify duplicated software in an enterprise, for example based on hashes of nodes' hierarchy and/or contents. Dependencies among copies of a piece of software may be merged into a common record by the synthesis agents.

Users may also be provided the ability to manually add planned assets and/or nodes to an enterprise's dependency graph. The manual addition of planned assets and/or nodes may also include the manual addition of planned dependencies in relation to other assets and/or nodes in the enterprise. Such planned assets and/or nodes may later be supplanted by actual assets and/or nodes as they enter the enterprise. In this way, the potential impact of adding planned assets and/or nodes to an enterprise can be forecast in advance without the need to find out in a live environment where dependencies may arise.

In one embodiment, a dependency graph or changes detected therein may form the basis on which rules governing an enterprise's software may be established and enforced. For example, a dependency graph provides a snapshot in time of dependencies and relationships among the nodes in an enterprise, each such dependency or relationship being depicted as a directed or undirected edge in the graph. Changes in an enterprise may be detected by examining changes to dependency graphs for the enterprise over time.

For example, in one embodiment, shown generally in FIG. 2, a delta agent 102 running on an asset 100 in the enterprise or at a third party asset such as a cloud computing instance or third party software as a service provider may be configured to receive dependency graphs 104 from a synthesis agent 106. The delta agent 102 may be configured to examine newly received dependency graphs and to compare them to previously received dependency graphs. As a result of such analysis, changes to the nodes themselves (e.g., a change to one or more lines of code of a particular piece of software), changes to node hierarchies, and changes to node dependencies may be detected.

Detected changes may take different forms according to the particular aspects of the enterprise. For example, a change to a node may be any one or more of the addition to a node (e.g., an added line of code), a modification to a node (e.g., a changed parameter in the code), and a deletion from a node (e.g., a removed table column). At a higher level, a change may take the form of a node that is added to the enterprise, a node that is modified, and/or a node that is removed from an enterprise. Changes may also take the form of an added dependency between nodes, a modified dependency, and/or a removed dependency.

Changes detected in an enterprise over time may be recorded in an audit trail 108, for example in the form of a change graph visually presented to a user that visually depicts changes to nodes, edges, etc. Changes may be depicted as, for example, application of a color or other visually identifiable notation based on a type of change detected to a depiction of nodes and edges present in the enterprise. Such an audit trail may also be configured to depict information about the change, for example a time that the change was detected, a user responsible for making and/or approving the change, etc. In another example, an audit trail may be configured to depict a last change time representing the last time that a change was detected for a particular node or edge. Together with the changes made over time, a change graph may be configured to allow a user to select a historical dependency graph for visual presentation in order to show the state of the software in the enterprise at a historical point in time.

In one embodiment, shown generally in FIG. 3, a governance engine may be provided with a rule agent 110 that is configured to receive one or more rules (from a user, an owner or administrator of the enterprise, a third party, etc.) 112, each rule specifying at least one trigger and at least one output. Examples of triggers include a change in a dependency graph, for example, a change in node hierarchy, a change within a node, the addition or removal of a node, a change in an edge, etc. Triggers may also be configured in connection with various agents as discussed below. In addition, triggers may be configured in connection with any aspect of a node or edge. For example, a trigger may be configured based on the content of code comprising a node (e.g., based on an inspection of software code for a particular operand or variable, inspection of table columns for data that appears to be Social Security numbers, etc.), the geographical location of an asset node, the author of a node (e.g., whether the author is a low-level employee or an administrator, etc.), the direction of an edge, etc.

Triggers may be specified at any level of a hierarchy. For example, a trigger may be specified with respect to a particular node, with respect to a particular node and all or some of its children, etc. For example, a rule trigger may be configured to activate if a change is detected in a particular library or in any function contained in that library.

In addition, triggers may be specified in connection with a dependency from a particular node. For example, a trigger may be configured to activate if a change is detected in any node upon which a particular node is dependent.

Triggers may also be specified using various levels of logic sophistication or complexity. For example, a trigger may be specified in a binary form (e.g., a change happened or it did not), a multivariate form (e.g., an addition occurred, a modification occurred, and/or a deletion occurred), etc. Logical conjunctions may also be specified, such as the operands IF, AND, OR, NOT, etc. For example, a trigger may be configured to activate only when a change occurred in node A AND in node B. As another example, a trigger may be configured to activate when an addition occurred within node C OR node D, but NOT if a change occurred in edge E. Accordingly, triggers may be grouped into any number of levels of a trigger hierarchy.

A governance engine may also comprise a security agent 114 configured to check an enterprise and/or new nodes added to an enterprise against a list of allowed or not allowed elements and/or a list of elements with known security issues 122. For example, a security agent may be configured to check all new nodes detected in an enterprise against a list of Common Vulnerabilities and Exposures (CVE) maintained by the enterprise or by a third party, for example, the U.S. National Vulnerability Database and/or a list published at cve.mitre.org. A rule trigger may be configured in connection with such a security agent. For example, a trigger may be configured to activate if a new node detected in an enterprise is identified in a CVE list published at cve.mitre.org.

In another aspect, a governance engine may also comprise an open source agent 116 configured to check an enterprise and/or new nodes added to an enterprise against a list of open source software or category of open source software 124. For example, an open source agent may be configured to check all newly added nodes against a list of common open source software that has been established by an enterprise administrator for the purposes of making sure that none is used in an enterprise. In another example, an open source agent may be configured to check newly added nodes for open source software having unfavorable license terms, by examining the new nodes themselves for mention of accompanying license terms and/or comparing new nodes against a list maintained by the enterprise and/or a third party of elements known to be associated with unfavorable license terms. A rule trigger may be configured to activate in connection with such an open source agent. For example, a trigger may be configured to activate if a new node is detected in an enterprise that contains within it mention of being associated with a GNU license.

In one embodiment, a rule or trigger set comprising one or more rules or triggers may be input to a governance engine. Such a rule or trigger set may be configured by an enterprise administrator or a third party. For example, an EU Data Privacy trigger set may be configured by a third party to contain triggers aimed at detecting changes to an enterprise that could violate certain data privacy requirements of the European Union, for example, non-permitted uses of sensitive personal information recorded in certain columns of a table within the enterprise. Such a rule or trigger set may input as, for example, a JSON-based text file.

As discussed above, each rule enforced by a governance engine specifies at least one output. Examples of possible outputs include sending a notification to a particular user or administrator (e.g., via email, text message, etc.), publishing a notification to a message queue (e.g., a Slack channel, a message board, etc.), blocking a change triggering the rule, requesting permission from an administrator before a change triggering the rule is permitted to go live in the enterprise, reversing a change implemented in an enterprise by reverting the node or edge back to a prior version, etc.

In one example, a governance engine is configured to perform a pre-clearance check of changes proposed by certain categories of users before they are permitted to go live in an enterprise. For example, a governance engine may be configured in connection with a development environment. In this example, a delta agent 102 may be configured to analyze proposed changes to nodes or edges in an enterprise and input any detected changes 118 to such a governance engine 120. The governance engine then enforces rules pertaining to the proposed changes, for example, sending (as an output) an approval request to an administrator if a proposed change activates a pre-configured rule trigger.
